At its inception the series of volumes that were to 
be included under the title "The Fauna of British India" 
was limited to seven, which were to deal with the Verte- 
brata only. On the recommendation of the then Govern- 
ment of India the Secretary of State for India sanctioned 
the preparation of these volumes in 1883; but the first 
volume to be published, that on the Mammalia by W. T. 
Blanford, F. R. S., did not appear till 1888. 

The geographical limits of the fauna to be studied 
were defined in the preface to this fiirst volume as com- 
prising " the dependencies of India, with the addition of 
Ceylon, which, though British, is not under the Indian 
Government. Within the limits thus defined are com- 
prised all India proper and the Himalayas, the Punjab, 
Sind, Baluchistan, all the Kashmir territories, with Gilgit, 
Ladak, etc., Nepal, Sikkim, Butan, and other Cis-Hima- 
layan States, Assam, the countries between Assam and 
Burma, such as the Khasi and Naga hills, and Manipur, 
the whole of Burma, with Karennee, and, of course, 
Tenasserim and the Mergui Archipelago, and lastly the 
Andaman and Nicobar Islands. Afghanistan, Kashgaria, 
Tibet, Yunnan, Siam, and the Malay Peninsula south of 
Tenasserim are excluded". 

When the volumes dealing with the Vertebrata were 
completed the series was extended to include the Lepidop- 
tera and thereafter the Insecta in general. A few years 
later it was realised that the series was in danger of becom- 
ing overloaded with works on the insects to the almost 
complete exclusion of all the other groups of animals, 
the only exception being the Arachnida, which were re- 
ported on by the late R. I. Pocock, F.R.S., in 1900. In 1908 
the first of a series of volumes on the Mollusca was pub- 
lished and this was followed at intervals by three other 
volumes on this group. In 1909 the sanction of the Sec- 


retary of State for India was granted for the preparation 
of volumes on the Freshwater Sponges, Hydroids and Poly- 
zoa by the late Dr. Annandale, and on Leeches by Mr. 
Harding and Prof. J. Perq^ Moore. In the same year it 
was decided to extend the series so as to include the marine 
fauna of the Indian coasts, and sanction was accorded for 
the preparation of two volumes on the Brachyura by the 
late Lieut.-Col. Alcock, F.R.S.; but Alcock's retirement 
from India and pressure of work in other spheres prevent- 
ed the preparation of these volumes. In 1922 the Secretary 
of State for India was asked to sanction the preparation 
of a volume on the Madreporarian Corals, but he decided 
for financial reasons to postpone for a time consideration 
of any further volumes in the 'Fauna' series. 

When the consideration of further volumes was again 
taken up the marine fauna was not lost sight of and 
sanction was granted by the Secretary of State for India 
for the preparation of several volumes on groups of the 
marine fauna, and with the steady growfh ot our know- 
ledge of the deep-sea fauna of Indian seas it was decided 
that this should be included, thus widening very consider- 
ably the scope of such volumes. The volumes on the 
marine fauna, that have up to the present time been sanc- 
tioned, are:— 

Sponges . . by M. Burton. 

Echinoidea . . by Th. Mortensen.^ 

Polychaeta . . by P. Fauvel. 

Cirripedia . . by C. A. Nilsson-Cantell. 

Copepoda Calanoida . , by R. B. Seymour Sewell. 

Brachyura, Oxyrhyncha . . by B. N. Chopra, 

and Pelecypoda . . by Baini Prashad. 

The preparation of a 2nd Edition of the volumes 
on Fishes was also entrusted to Dr. S. L, Hora. 

With the extension of the series to include the deep- 
water fauna it has become necessary to define the bound- 
aries o£ the ocean within which the fauna may be con- 

iThe death of Dr. Mortensen, since this was written, has 
rendered the authorship of this volume vacant. 



sidered to belong to Indian waters and the following 
limits have been accepted :— 

On the west the area shall be bounded by the meri- 
dian o£ lat. 60°E. as far north as Ras-al-Had, and thus 
includes the Gulf of Oman and the Persian Gulf. 

On the south by the latitude 1°S. so as to include the 
whole of the Maldive Archipelago. 

. On the .east by the coast of Burma, by a line drawn 
from Victoria Point to the northern tip of Sumatra and 
by the west coast of Sumatra as far south as Lat. 1° S. 

The area thus enclosed is shown in the accompany- 
ing map, which also indicates the various sub-marine 
ridges and basins that lie wholly or in part within the 
boundaries of the Indian region. It is, of course, well 
known that this area is populated by an Indo-Pacific 
fauna and hence a certain amount of latitude must be 
granted to Authors who wish, for one reason or another, 
to include in their account of the Indian fauna certain 
species that up to the present time have not been captur- 
ed within these waters but whose presence there may con- 
fidently be expected, and this is all the more necessary 


since the land region has now been extended beyond the 
original scope to include Malaya, where this is possible. 

As a consequence of the recent change in the Govern- 
ment of India and the division of this region into two new 
Dominions of India and Pakistan it has become necessary 
to change the title of the series. In future the series will be 
known as "The Fauna of India", and the Government of 
India have decided that the area to be covered shall in- 
clude India, Pakistan, Ceylon, Burma and, if possible, 
Malaya. It has also been decided that henceforth the 
volumes of the series shall be printed in India. The 
present volume thus becomes the first of a new series. 

Acknowledgment and the thanks of both Author and 
Editor of this volume are due to a number of Scientific 
Societies and other bodies for permission to reproduce 
illustrations that have previously been included in the; 
Journals and Memoirs published by them. First and fore- 
most among these is Dr. Chopard and the " Federation 
Francaise des Soci^t^s de Sciences Naturelles ", to whom we 
are indebted for permission to reproduce a large number 
of figures from Dr. Fauvel's Monographs on the 
" Polychetes errantes " and " Polychfetes s^dentaires " in the 
"Fauna de France": Other scientific bodies, to whom our 
thanks are due, are the Trustees of the British Museum 
(Natural History), the Royal Society of London, the 
Linnean Society of London, the Zoological Society of 
London, the Musdum d'Histoire Naturelle de Paris and 
the Soci6t6 Zoologique de France, and to Messrs. Taylor 
and Francis, the Publishers of the " Annals and Magazine 
of Natural History ". Finally, our thanks are tendered 
to the Director of the Zoological Survey of India for per- 
mission to reproduce many figures that have been publish- 
ed in the "Records" and "Memoirs of the Indian 
Mtiseum ".

Previous to the year 1861 very little -ivas known con- 
cerning the Polychaetous Annelids of India. 

L. K. Schmarda, in the course o£ a journey round the 
world (1853—1857) , spent several months collecting in 
Ceylon and in his Report " Neue wirbellose Thiere " 
(1859—61) * he desaibed about a score o£ Polychaeta 
from that island. Unfortunately Schmarda's descriptions 
are generally too vague and too scanty to allow of an 
accurate identification. 

In Grube's short paper on the Ceylon Annelids (1874) 
only six species are described. In W. Michaelsen's 
" Polychaeten von Ceylon" (1892) fifteen species were 

By far the most important work on the subject is A. 
Willey's " Report on the Polychaeta collected by Prof. 
Herdraan at Ceylon" (1905) in which a large number 
of old and new species are described. It was followed 
by Southern's " Polychaeta of the Chilka Lake " (1921) ; 
Augcner's "Ceylon Polychaeten" (1926) and "the Lit- 
toral Fauna of Krusadai Island, in the Gulf of Manaar; " 
" Chaetopoda ", Part I, by Gravely (1927); Part II by 
Fauvel (1930). 

But all these papers are relative to Ceylon and its 
vicinity and the coasts of the Madras Presidency. As for 
the other parts of India, with the exception of S. S. Bindra's 
" Fauna of Karachi " (1927) , only casual mention, here 
and there, of a few species are scattered in papers not 
specially dealing with India. But later the collections of 
the Zoological Survey of India and of the Indian Museum, 
Calcutta, have afforded us much more extensive know- 
ledge concerning the Polychaeta, not only from the coasts 
of India but also from the neighbouring Seas. Three 
hundred species were recorded in Fauvel's Report (1932) . 

* Foi full references concerning the papeis mentioned see the 
Index at the end of the volume. 

F. 3 


The range of the area dealt with in the present work 
extends from Long. 60° E, as far as Cape Ras-al-Hadd, 
on the western side; the whole of the Persian Gulf and 
the Baluchistan Coast forming the northern boundary; 
to the east, the region includes the Malacca Strait, as far 
as Singapore, whilst the Southern boundary is Lat. 1°S, 
so as to include the whole of the Maldive Archipelago. 

On the Persian Gulf, the Arabian Sea, the Gulf of 
Oman, the Bay of Bengal, the Maldive and Mergui 
Archipelagoes information as regards the Polychaeta is 
very plentiful but is scattered in a large number of 
Reports oi various expeditions. 

Thus we have been able to record 450 species from 
the given area. Nevertheless, this rather high number 
hardly represents more than about one-half of the pro- 
bable total number of the Polychaeta, for, owing to the 
well known ubiquity of these worms, nearly every 
species of the Indian Ocean and of the warm parts of 
the Pacific is likely to be found in the area of the Indian 
Fauna, as delimited above. 

Having had the good fortune to be able to study 
three hundred species of the Indian Museum, one hun- 
dred and nine of the Madras Government Museum, and 
the material of several expeditions to the Red Sea, Per- 
sian Gulf, Indo-China, New Caledonia, Australia and 
Gambier Islands, nearly all of the 450 species here des- 
cribed have been in my hands, the few exceptions being 
some rare ones, the description of which I have taken 
from the original authors. 

The Polychaete Fauna of India does not materially 
differ from that of the Gulf of Siam, Malay Archipelago, 
China Sea, Philippines, Great Barrier Reef, Australia, 
New-Caledonia, and a great part of the Pacific. It must 
also be borne in mind that many Polychaetes are really 
cosmopolitan. Out of the 450 species here recorded 108, 
nearly one-fourth, are also European species. 



The Polychaeta and the Oligochaeta are two impor- 
tant divisions of the Chaetopoda, annulated worms en- 
dowed with locomotive bristles or setae. But the bristles 
of the Oligochaeta are few and directly set on the body- 
walls, which are destitute of parapodia or feet. Other 
appendages are also wanting. On the other hand, the 
bristles of the Polychaeta are usually very numerous and 
borne on clearly marked parapodia, lateral expansions, 
or feet, of the teguments. The body generally carries 
various appendages such as tentacles, palps, cirri, bran- 
chiae, etc. Moreover, the Polychaeta are very generally 
marine animals with separate sexes, whilst the Oligochaeta 
live in fresh water or damp earth and are hermaphrodite. 


Fig. 1. 

The body is generally elongated, with numerous 
segments. It consists of a Prostomium or anterior cepha-

c, Calluona (Alciopid); d, Glycera (Glycerid); e. Nereis;

and tube (Serpulid). 


lie lobe, a Metastomium including all the following seg- 
ments, and a Pygidium, the last segment. 

A few anterior segments, more or less modified, may 
be fused with the prostomium to form a kind of head with 
■various appendages such as antennae or tentacles, palps 
and tentacular cirri. 

In the Errantia, the segments of the metastomium are 
often very numerous and nearly all alike, as in the Nere- 
IDAE, Syllidae, Eunicidae, ctc, whilst in the Sedentaria the 
body, sometimes shorter, is often clearly divided into 
distinct regions such as thorax, abdomen, and tail. 

The prostomium, a cephalic lobe, the anterior part 
of the so-called head, is sometimes reduced to a mere 
cone, blunt or sharp, and destitute of any appendages, 
as in Lumbriconereis. It is a long annulated cone, 
with four small tentacles at the tip, in Glycera; square or 
scute-like in Nephthys; more or less complicated with 
several appendices in Nereids, Aphroditidae and Euni- 
cidae; or reduced to a mere ridge in Sabellids and Serpu- 

The prostomium generally carries one, two or more 
pairs of eyes, mere eye-spots, single or compound, or 
sometimes highly differentiated organs such as the big 
red eyes of the Alciopids, with a cornea, a lens and a 

Appendages (Fig. 2) . 

The appendages of the Polychaeta are various pro- 
cesses of the teguments which may be classed into two 
groups. The first are merely epidermic solid projections, 
as the styles and stylodes. The others are hollow and 
are formed by an evagination of the body wall. 

When the antennae, palps and cirri are borne on a 
hollow base, this last is termed ' phore '. Such an antenna 
is then divided into a solid distal part, or ceratostyle, and 
a basilar hollow part or ceratophore; a palp is divided 
into a palpostyle and a palpophore a cirrus into a cirro- 
style and a cirrophore. 

Amongst the cephalic appendages are: (1) the palps, 
innervated by a large nerve issuing from the anterior 
part of the brain. They may be simple, elongated, pre- 
hensile (Spionioae) or short, simple, or articulate (Sylli- 
dae, Nereidae) ; (2) the antennae or tentacles, innervated 
from the middle brain; (3) the tentacular cirri, borne on 



the metastomium (buccal segment) , or on the segments 
fused with the prostomium to form the head. 

The Parapodia, or feet, are more or less complicated 
lateral processes of the body-wall. These organs, with the

bristles they carry, provide the most important features 
for the identification of the species. Typically, each 
segment carries one pair of parapodia divided into two 
rami, a dorsal one, or notopodium, and a ventral or neu- 
ropodium. When both rami are borne on a common 
base the biramous foot is said to be monostichous; when 
both rami are quite distinct and more or less apart, as in 
most Sedentaria, it is termed distichous. (Fig. 3) . For 
instance, in a biramous parapodium of Nereis there are; 
(1) two setigerous lobes (or chaetigerous sacks) carrying 
the setae and supported by a stout, enclosed, bodkin-like 
bi-istle or aciculum; (2) parapodial lobes, lips or fillets; 
(3) a dorsal and a ventral cirrus. Branchiae, or gills, 
simple or branched may be inserted upon the dorsal 
ramus or between the two rami. 


The parapodia are biramous when both rami axe 
nearly equally developed; subbiramous with a dorsal dr-

In the Sedentaria the neuropodia, or ventral rami, are 
often reduced to mere transverse ridges, or uncinigerous 
tori, destitute of a cirrus and carrying short hooks or 

Setae (or chaetae) are chitinous bristles which are 
very important for the classification and are of very varied 
shapes and disposition. They may be divided into two 
groups: (1) the setae s. str., or bristles, and (2) the uncini, 
avicular or acicular hooks. 


The setae are simple, jointed, or compound. They 
may be long, slender, filiform, hair-shaped, capillary, 
smooth or spinulose, curved, flat, limbate, or winged on 
one or both sides, with frills or transverse rows of spines, 
geniculate, trumpet-shaped, exceptionally forked at the 
tip, etc. (Fig. 4) . When they are short, stout, bodkin-

shaped, or flattened, paddle- or oar-shaped, they are called 
paleae. The articulated, or many-jointed setae of the 
Chloraemidae and SIGALIONINAE are a connecting 
link with the compound setae with a basal part, or stalk, 
and a terminal piece elongate, needle-like, or short, sickle- 
shaped. When both sides of the articulation are the 
same length it is termed komogomph, and heterogomph 
when they are unequal. 

The ventral uncini of the Maldanidae and Capi- 
TELLIDAE are sigmoid hooks with a rostrum, a guard, and 
a manubrium. The uncini of the Sedentaria are often 
short denticulate plates, such as the avicular hooks of 
the Sabellidae and Terebelledae, with a broad basal 
manubrium and a beak-like hook, crested with denticles 


on the vertex. They are set on the tori in one or two 
parallel rows. (Fig. 5) .

Proboscis. Many Errantia are provided with an 

eversible proboscis armed with strong horny jaws, or 

beset with papillae, or with chitinous denticles, or 

The intestine is generally straight, rarely coiled, 
sometimes with glands or diverticula. 

Body cavity. In the Errantia the body-cavity, or 
coelom, is generally divided by numerous intersegmental 
septa, or diaphragms. In the Sedentaria these septa are 
few and generally restricted to the anterior part of the 

Muscles. The muscles are smooth, set in circular 
layers and stout longitudinal fascicles. Oblique muscles 
run from the sides to the middle of the ventral side. 

Nephridia, or excretory organs, are disposed in pairs 
on succeeding segments with lateral pores opening on 
the sides near the feet. In the Sedentaria, they are gene- 
rally reduced to a few thoracic pairs. The anterior ones. 


in front of the diaphragm, are purely excretory organs, 
whilst the others are also used as genital ducts. 

The vascular system is generally closed and well 
developed, sometimes very complicated and offering many 
variations. The dorsal vessel is contractile, but special 
organs of propulsion, or hearts, may also exist. 

The blood is red, or emerald green in Sabellidae, 
Serpulidae, Chloraemidae, but is often uncoloured. 
The respiratory pigments, haemoglobin or chlorocruorin, 
are in solution in the plasma, only very exceptionally in 

Respiration is effected by means of branchiae or gills, 
of which there are two kinds: (1) genuine branchiae, 
with vascular loops, and (2) lymphatic gills destitute of 
vessels and filled with coelomic fluid. The gills exhibit 
very numerous and varied types. They may consist of 
simple filaments, straight or coiled, forked or pectinate, 
set on the dorsal rami of many feet, or branched or bushy 
and restricted to the anterior segments, disposed as a 
terminal funnel of many filaments on the head of Sabel- 
lids and Serpulids, etc. 

Sense organs. The sense organs are the eyes, the 
nuchal organs, the lateral organs and the statocysts or 
otocysts. The eyes are not always restricted to the 
prostomium. The branchial filaments of the Sabellids 
often bear dorsal or subterminal eyes. The Opheliidae 
have lateral eye-spots disposed on a number of segments 
and the pygidium of little Sabellids may carry several 
eye-spots. We have already mentioned the large eyes of 
the Alciopidae. The lateral organs are small ciliated 
cups, or knobs, present on a number of segments in the 
Capitellidae, Opheliidae, Aricudae, etc. 

Otocysts, or statocysts, exist only in very few species 
(ARENicoLmAE, Arichdae, Terebellidae and Sabellidae) . 

Colour. Many species are adorned with bright 
colours and variegated patterns. Unhappily, these colours 
do not keep well in the preservatives, formol or alcohol. 
They are due to the red, or emerald green, blood and 
to solid or dissolved pigments of the epidermis, such as 
Haemoglobin, Chlorocruorin, Haemerythrin, Tetronery- 
thrin. Melanin, Uranidin and various Lipochromes. 
These pigments, with the exception of Melanin and a 
few others, are either dissolved or altered by the preser- 
vative fluids.

On the other hand, the splendid iridescence of the 
bristles of Aphrodita and ChloraemidaEj as well as of the 
body-wall oi Eunicids and others, displaying all the 
changing hues of the rain-bow, are permanent for they arc 
caused by diffraction of the light either by the numerous 
very fine striae of the setae or the very thin lamellae of 
the cuticle and these structures are not affected by the 

Phosphorescence is not restricted to the Syllids and 
other small pelagic species which abound in the plankton; 
it is also a property of many Annelids creeping on the 
rocks and algae, and even of tubicolous species. For 
instance, the luminescence o£ Chaetopterus, living on the 
bottom inside a thick parchment-like tube, is the most 
beautiful of all. 


The sexes of the Polychaeta arc usually separate and 
even sexual dimorphism may occasionally occur. Never- 
theless, a few species are hermaphrodite, especially amongst 
Sabellidae and Serpulidae. The ova and spermatozoa 
are discharged into the sea. The fertilised eggs give rise 
to a floating Trochophore larva, and then to post-larval 
stages dropping to the bottom or swimming for a long 

Asexual reproduction, Blastogamic or Schizogamic, 
is frequent amongst Syllids and a few other Polychaeta. 

Epitoky. A number of Polychaeta, especially amongst 
Syllidae, Nereidae and in a few Eunicidae, undergo a 
peculiar metamorphosis at the epoch of reproduction, ac- 
quiring new long swimming bristles, and developing large 
foliaceous lobes on the feet, whilst the eyes grow larger. 
For instance, in Nereis, the eyes become larger, a few of 
the anterior dorsal cirri grow thicker at the end, but the 
anterior segments are not otherwise materially altered; 
the middle and posterior segments, however, become 
flattened and crowded together, the enlarged feet develop 
broad foliaceous lamellae, and shed their bristles which 
are replaced by new oar-shaped swimming setae. When 
maturity is perfect and the metamorphosis complete, these 
Heteronerets stages rise in swarms to the surface of the 
sea, shed their sperm and ova, and then die. In the 
case of the " Palolo " (Eunice viridis) , an Eunicid of the 
Pacific, the posterior part of the worm, a little modified 
.and filled with genital products, breaks off from the ante- 


rior part, which remains in the coral reefs, and rises in 
swarms to the surface where it is taken up for food by the 
natives. Singularly enough the rise of the " Palolo " is 
connected with lunar phases. It is very probably the only 
instance of an edible Polychaete. 

Autotomy and Regeneration. 

Autotomy is wide-spread amongst Polychaeta. The 
POLYNOINAE easily shed their elytra, the Spionidae their 
palps, the Ampharetidae and Terebellidae their gills or 
their tentacular cirri. Many Euniodae, Capitellidae and 
others are so brittle that it is but too often difficult to 
obtain a whole specimen. 

This propensity to autotomy is counterbalanced by a 
great facility of regeneration and may be turned into a 
mode of asexual multiplication as in Phyllochaetopterus 
and Dodecaceria. It is not uncommon to find a more or 
less long fragment of the mid-body of an Eunicid having 
regenerated both a head and a tail. In Procerastea and 
Dodecaceria a fragment composed of two segments, or 
even a single segment, may thus regenerate a whole worm. 


As already stated the Polychaeta are marine animals; 
nevertheless a few species can live in brackish water and 
even, though infrequently, in fresh water. In the brack- 
ish water of the Chilka Lake, the Salt Lakes near Calcutta, 
the Gangetic Delta, and the Taleh Sap, for instance, a 
few genuine marine species occur with several others 
more closely adapted to water of low salinity, such as two 
small Nephthys, Dendronereides heteropoda, two Capi- 
tellidaEj and two small Serpulidae, Ficopomatus macro- 
don and Mercierella enigmatica. But species living in 
fresh water, or water of so low a salinity as to be drinkable, 
are of much rarer occurrence. Such are however several 
Lycastis and a few other Nereidae, several Sabellidae of 
the Baikal Lake, Mercierella enigmatica of world-wide 
distribution in estuaries and rivers, and another little 
Serpulid, Marifugia cavaiica, found living in the deep 
caves of the Karst Region. 

The Polychaetes are plentiful on the shore between 
tide-marks, on coral reefs, and in the shallow littoral 
waters as far as 200 fathoms, but beyond this, as the depth 
increases, the number of species rapidly decreases and they 


become very scarce in the deep-sea dredgings. But, 
singularly enough, in the deep-sea faima many shallow- 
water species are found associated with rare genuine 
abyssal forms. For instance, Amphicteis gunneri, often 
collected between tide-marks, has been dredged by the 
Prince of Monaco in 1885 metres, and in 2750 £ms by the 
" Challenger ", and the common shore Serpulids, Hydro- 
ides norvegica and Pomatoceros triqueter, at 4808 m. 

Polychaeta are hence very little affected by depth and 

Genuine pelagic species, usually transparent, and 
numerous larval and post-larval forms are part of the 

For the most part, the others live on the bottom, 
boring in the sand or mud, fixed on stones or shells, creep- 
ing amongst algae, or burrowing in the crevices of rocks 
and corals, or amongst stones and shells incrusted with 
calcareous algae. Sponges, Ascidians and Polyzoa. Some 
are commensal or ectoparasitic on Hydroids and Echino- 

Several of the so-called Errantia live nevertheless in- 
side tubes, whilst true Sedentaria are sometimes tubeless 
or vagabond. The limivorous species swallow mud or 
muddy sand, like the earthworms. The Sabellids and 
Serpulids, which cannot leave their tubes, feed by means 
of their branchial tufts, the radii or barbules of which 
collect the plankton and the small particles of food float- 
ing in the water and their cilia carry them to the mouth. 
Certain Errantia, the proboscis of which is armed with 
stout horny jaws, such as the Aphroditidae, Nereidae and 
EuNiciDAE are prowling and hunt living prey. 


Most of the species of Polychaeta have a very wide 
distribution and many are quite cosmopolitan, so that 
they cannot be grouped into Zoological Provinces. For 
instance, amongst the 450 species, here recorded from the 
Indian area, 108, nearly a fourth, are common on the 
western shores of Europe. 

A comparison of the genuine pelagic Annelids of the 
plankton of Indo-China shows a nearly complete identity 
with those of the Atlantic. 

Many of the Arctic circumpolar Annelids, with the 
exception of a few peculiar species, are also found in the 


temperate Atlantic and Pacific Oceans. In the tropical 
area, whilst many disappear in the littoral zone, a number 
of them is still to be found in the deep-sea dredgings, and 
some of these northern species reappear on the temperate 
or cold shores of the south-hemisphere. 

Antarctic species reach to the south parts of America, 
Australia and Africa. 

Most of the intertropical species are also the same all 
round the world. 

In the Fauna of Japan both arctic and tropical forms 
are found. This is easily explained. Two streams run 
along the coasts of Japan: a cold one, the Oja-Siwo, runs 
down from the glacial Arctic Ocean along the coasts of 
Kamchatka, Manchuria, Korea and the North-West coast 
of Japan, bringing with its cold waters the northern species 
of Polychaeta, whilst the Kuro-Siwo brings to the Eastern 
coasts the warm waters of the tropical Pacific with part 
of their fauna. 

In short, the distribution of the Polychaeta is mainly 
regulated by the temperature. In the great depths of 
the Oceans the temperature is both very low and very 
uniform all over the world and the Annelidan fauna is 
also very uniform and contains moreover a number of 
arctic species which find there the same cold temperature. 
For the same reason, in the intertropical area the shore 
and shallow-water species, especially those of the coral 
reefs, finding the same conditions in the three oceans, are 
nearly all identical. 

The Polychaeta are indeed very sensitive to the 
temperature and an abrupt rise or fall of a few degrees 
sometimes kills them outright. 


Pelagic Annelids are easily procured by the towing 
of a plankton net. Night fishing with artificial light will 
thus procure a lot of Syllids, epitokous Nereids and many 
rare small species and larvae. Shore collecting will yield 
the most varied and abundant crops; 

The necessary implements are a stout spade, a crow- 
bar, a chisel and a canvas bucket, or a fisherman's basket 
with several glass jars and a number of glass tubes. 

Care must be taken to separate large predatory species 
such as Nereids, Eunicids and Aphroditians. These large 
and ravenous species, whilst being carried home, are 


better kept in damp sand or amongst algae than in water 

Many species burrowing in sand or mud are caught by 
turning it over with the spade. Each clod must be care- 
fully broken into small parts with the fingers, avoiding 
any injury to small and delicate species. The sand may 
also be washed through a sieve in little pools of water. 

Many Annelids are to be found creeping on stones 
or algae or in tubes incrusting them. Loose stones should 
be carefully turned over and examined, and should then 
be replaced in their previous position to avoid the decay 
of the fauna fixed on the upper surface. The crow-bar 
is used to rip open the crevices of rocks and corals in 
which a very rich and varied fauna is usually found. 

In dredging and trawling, when the dredge or trawl 
comes on board, and the contents are scattered on deck, 
it is easy to pick up the large specimens. To search the 
rubbish for small species, shells and stones coated with 
Serpulids, Polyzoa, Algae, etc., should be put into broad, 
shallow, glass vessels, or, better still, into white china 
wash-hand basins, with sea water. When the water be- 
comes putrid the small boring species and others ensconced 
in tubes or crevices come out and reach the edges of the 
vessel where they can easily be picked up. 


The best preserving medium for Polychaeta is 70— 
75% alcohol. Formalin is very bad, quite detrimental to 
good preservation for the specimens rapidly become soft, 
sticky and nearly useless. Nevertheless, in an emergency, 
and for large species, it may be used for a short time pre- 
vious to spirit (5% of the commercial solution of forma- 
lin) . On the other hand, when specimens have been 
first hardened in strong spirit they may next be kept in 
formalin with less inconvenience. 

For histological purposes, Bouin, Brasil or Zenker 
fluids are amongst the best. 

Delicate and brittle species must be naroctised pre- 
viously to fixing in spirit. This is easily done by adding 
very gradually, small quantities of alcohol (up to 5% or 
10%) to the sea water. Other anaesthetics such as cocaine, 
chloral, etc., may also be used for the same purpose. To 
avoid too great a contraction of large species they may 
first be put into very weak spirit (30—40%) and be 


kept well stretched with pincers; or bamboo or horn 
spatulae, and as soon as they cease to react they should 
be immersed in 70—90% alcohol. To ensure a good 
preservation the volume of alcohol must be gi-eater than 
the specimen's and it must be renewed after a few days. 
Preserved specimens should be kept separate in glass 
tubes, the smaller ones, in small tubes with a cotton-wool 
stopper, are packed together in larger vessels filled with 
70—75% alcohol. The paper, or parchment, labels must 
be put inside the tubes with inscriptions, in pencil or 
permanent Indian-Ink, carefully noting the date and 
locality, the colour of the living animal and other parti- 


To identify a specimen it is necessary carefully to note 
the divisions of the body, if any, the form of the prosto- 
mium, the eyes, the tentacles, tentacular cirri, gills, and 
the proboscis with its jaws and denticles, when there is 
one. Next in importance are the parapodia or feet with 
their bristles of high specific value. But as the structure 
of the feet and the form of the setae often vary materially 
in the anterior, middle and posterior parts of the body 
it is always necessary to examine a number of them. This 
is easily done by tearing, or cutting, with sharp pincers, 
or scissors, a whole series of feet, say nine for a Nereis, 
and disposing them in three rows on a slide, three ante- 
rior, three median and three posterior ones, the relative 
numbers of the segments they belong to being carefully 
noted on the label. 

If a permanent preparation be wanted, rapidly drain 
the alcohol from the slide and before the parapodia get 
dried drop on them a small quantity of melted gelatm- 
glycerin, put on a cover-slip and warm slightly, if neces- 
sary; the preparation will then keep for years. 

Mounting in Canada balsam is not recommended, the 
setae— unless previously coloured— becoming too trans- 
parent and the fine structures indiscernible.

Remarks: Though Willey attributes 24 pairs of ely- 
tra to his species, his description and figures fit 
very well with Scalisetosus longicirrus. As the 
elytra were all wanting on his specimen he may 
have made an error regarding the number of 
elytra bearing segments.

grooves under the smooth lobe. About five buccal seg- 
ments. Dorsal setae very variable in length, of three 
kinds: (1) long calcareous setae, with an elongate slen- 


der tip, more or less serrated, and a small spur at the base; 

(2) large straight, harpooned, glochidiate setae, with 
lateral rows o£ easily deciduous teeth, and (3) stout, 
straight, smooth setae. Two kinds of ventral setae: (1) 
stout furcate setae with unequal aims, the larger one 
smooth, or slightly serrated on young specimens, and 

(2) a few sub-furcate setae with one of the arms thin 
and greatly elongated. Acucula short, spear-headed. 

Length: 50-200 mm. by 10-15 mm. 

Colour: Gills red, setae alabaster-white. 

Occurrence: Mergui, Andaman Islands, India, Cey- 
lon, Maldive Archipelago, Arabian Sea. 

Distribution: On coral reefs of the whole tropical 
area of Pacific, Indian and Adantic Oceans. 

Remarks: The setae, in life, are very brittle, and 
consequently vary much in length, according to the 
environment. As they are calcareous, they are often 
damaged in spirit, formol and other reagents, 
becoming soft, woolly and losing their lateral teeth. 
Moreover, many specimens, having undergone re- 
generations which are very frequent in this species, 
present marked modifications in the proportions and 
appearances of the head, the number oi buccal and anal 
segments, the shape of the body, of the anal funnel, and 
the length of the tentacles. Contraction, due to the fixa- 
tives, also alters the appearance of the caruncle to a large 
extent. Such is the explanation of its having been des- 
cribed under so many names. (See: Fauvel, 1 943a, p. 5) .

teriorly. The acicula have an elongated oval tip. Dorsal 
setae of two kinds: (1) slender elongated, bifurcated, with 
a long limb smooth or coarsely denticulated along its, 
internal border, and a short limb often reduced to a mere 
spur, and (2) short, stout, harpoon-shaped bristles. Ven- 
tral setae furcate, with the longer limh bent backwards 
and provided with a few faint denticulations. They are 
associated with a few slender elongate setae with a spur- 
like short limb and a long limb smooth, or faintly denti- 

Length: 30-220 mm. by .8-14 mm. 

Occurrence: Port Blair, Andamans; Chilka Lake.

Remarks If Amphinome djiboutiensis Gravier and 
A. maldivensis Potts, which i-eally belong to the genus 
Eurythoe, be also conspecific with E. paruecarunculata 
Horst, Gravier's name should have priority.

tomium is a blunt cone, destitute of eyes, tentacles and 
processes of any kind. Mouth broad. Proboscis soft, 
cylindrical, transparent, without any papillae. Pharynx

first five segments are slightly swollen. The feet consist 
of a blunt cylindrical setigerous lobe with a very small 
ventral cirrus. There is no dorsal cirrus. A stout acicu- 
lum, often reddish at the tip, does not protrude outwards. 
The setae are all simple, straight or slightly curved, and 
minutely hispid. In front view they look faintly bipecti- 
nate. Above the setigerous lobe a stout acicular bristle 
arises from a broad blunt cone, sometimes accompanied 
with a very slender, filiform capillary seta. Two short

Colour. In spirit, yellowish-white, with broad, round- 
ed, purple spots on the sides, encircling the feet. 

Occurrence: Taleh-Sap, Gulf of Siam (brackish 
water?) . Only two specimens known. 

Remarks: At first, I wondered whether this species 
were not an aberrant Eunicid; later, a comparison with 
Loandalia Monro and Ancistrosyllis Mcintosh suggested 
its attribution to the Hesionidae as more likely. The frag- 
ments of a worm from Annam which I attributed to 
Talehsapia (1935, p. 333) belong to a Loandalia spec, 
and not to the species from Taleh-Sap.

About "30 setigerous segments in the anterior or 
parent individual. The parapodia contain two acicula 
and numerous, upwards of 20, compound falcigerous 
setae; the head of the shaft is laciniate and the appendix 
js minutely bidentate and minutely fringed. The dorsal 


cirri are rather short, lanceolate, petaloid, with strong 
basal articulation. The second dorsal cirrus, i.e., the 
cirrus o£ the first setiger, is the longest. The rounded 
reduced palps, joined together in the middle line along 
their own length, are only visible from below. The 
pharynx is long and has a sigmoid flexure; it is armed in 
front with a circle of 44 denticles, larger and smaller 
irregularly alternating. The proventriculus shows 28 
glandular rows." (Willey.) 

In both specimens from Chandipore the parent stock 
has about 30 setigerous segments. One bears a single 
stolon and the other two. Augener has figured the free 
swimming male stolon or Polybostrichus. 

Occurrence: Ceylon; Orissa, Chandipore, near Bala- 
sore; taken at low tide on Ghaetopterid tubes,

Family NERETOAE Johnston. (Fig. 83) . 

Body elongated, rounded or somewhat flattened. 
Prostomium with four eyes. Two subulate tentacles. 
Two massive two-joint palps. Four pairs of tentacular 
cirri. Proboscis armed with a pair of horny jaws and, 
generally, a series of horny teeth (paragnaths) which may 
be arranged in eight groups. Feet biramous (except in 
Lycastis) after the second foot. Dorsal and ventral cirri. 
Dorsal ramus with 2—3 lobes or ligules, ventral ramus 
with two fillets and one lobe. Setae compound, spiniger- 
ous and falcigerous. Generally an epitokous, Heterone- 
reis, mature form. 

Remarks: The chief characters used for the identi- 
fication of Nereids are, first, those of the proboscis, next 
of the feet and, last, of the setae. The everted proboscis 
is armed, at its opening, with two lateral, horny, falci- 
form jaws, more or less denticulate. The trunk is divid- 
ed into two rings, an anterior distal, or maxillary ring, 
and an inferior, proximal, basal or oral ring. It is

divided into twelve areas on which are inserted the groups 
of homy denticles, or paragnaths. These areas are de- 
signated by Roman numerals as follows: Maxillary ring, 
dorsal median group I; two dorsolaterals II; ventral 
median III; two ventro-Iaterals IV; Oral ring, median dor- 
sal V; two dorso-laterals VI; median ventral VII; two

Parapodia: Those of the first two segments are uni- 
ramous, all the others biramous. Each ramus is support- 
ed by a strong, enclosed, aciculum avid bears 2—3 more or 
less flattened lobes, the size and form of which may vary 
materially and gradually from before backwards. The 
last ones are sometimes highly modified and then afford 
important features for identification. Consequently it 
is always advisable to examine carefully anterior, middle 
and posterior feet of any specimen. 

The setae more rarely afford specific distinctions. 
Typically, in a Nereid's foot, there is a dorsal bundle of 
homogomph, spinigerous setae, a ventral upper bundle of 
homogomph spinigerous and heterogomph falcigerous 
setae and a lower bundle of heterogomph spinigerous and 



heterogomph falcigerous setae. Moreover, in some spe- 
cies, there is an homogomph falcigerous seta in the 
dorsal ramus. Large simple ventral setae or hooks are

Prostomium broader than long, not notched between 
the tentacles. Four rather large eyes, with a lens, arrang- 
ed in a widely opened trapezium. Tentacles about the 
length of the palpophores. Palps stout, ovoid. Tenta-

transparent, with 5—6 teeth, the inferior ones blunt. 
Paragnaths missing on the oral ring. On the maxillary 
ring they are sharply conical, transparent, little conspicu- 
ous. Group 1=0 (or 1?); 11= small clusters of 3—4; III 
=a transverse row of 3; IV=small clusters of 2—5. Paro- 
podia: On the first 5—6 setigerous segments, the dorsal 
cirrus is more or less of the same lengfh as the dorsal 
ligule. The dorsal and ventral rami are divided each 
into two elongated conical ligules whose tip is already 
sligl^tly filiform in the upper dorsal one. The ventral 
cirrus is shorter. In the suceeding feet, the dorsal ligules 
become flagelliform (whip-like) and much longer than 
the cirrus. In the ventral ramus, the setigerous lobe is 
much elongated and divided at the tip into two filiform 
appendages corresponding to tjie two fillets. The ventral 
ligule is whip-like and nearly as long ^s the dorsal ligules, 
and the ventral cirrjj? is njudi shorter. Behind the 20th 
foot, the ligules still increase in length, especially the 



ventral one, and are more or less coiled. (The posterior 
feet are unknown.) The dorsal bristles are slender hom- 
ogomph spiningers. The upper ventral bristles are long 
and slender homogomph spinigers and heterogomph falci- 
gers; the lower ventral ones are hemigomph, or faintly 
heterogomph, spinigers and long heterogomph falcigers.

three ventral ones, with the intermediate one shorter. 
Dorsal cirrus about the same length as the upper ligule. 
Ventral cirrus short. Middle region: 20—24 segments. 
Dorsal ligule narrow, and about twice or thrice as long

yet found in the Indian area). 

In the atocous condition this species is very close to 
PL dumerilii. The chief differences lie in the armature 
of the proboscis. There is a small row of paragnaths in 
the groups II, which are missing in PI. dumerilii, and in 
groups VI a rectangular cluster, instead of the usual two 
rows. Such slight differences are hardly of specific value 
but, on the other hand, the proboscis agrees tolerably well 
with that of PI. polyscalma, whose atocous condition is 
still unknown. PI. fusco-rubida might, perhaps, be tliis 
atocous condition, as PL pulchella is the atocous condi- 
tion of a Heteronereis quite distinct from PL dumerilii. 

Length: 20—50 mm. 

Colour: Dark pedal glands. 

Occurrence: Persian Gulf. 

Distribution: Philippine Islands; Persian Gulf.

Platynereis dumerilii var. pulchella, Fauvel, 1911, p. 402, figs. 

In the atocoiis condition this species is so close to PL 
dumerilii that I considered it as a simple variety charac- 
terised by a single row of paragnaths in the groups VI, 
instead of two, and by slightly difEerent falcigers. In all 
but a few anterior segments, there are one or four dorsal

homogomph falcigers, the terminal piece with downward 
curved, smooth tip and conspicuous terminal ligament 
having its basal attachment as far down as the tip of 
the articular cup. 

But the epitocous condition is quite different from 
PI. dumerilii and close to that of PL polyscalma, differing 
only in the presence of the said dorsal homogomph falci- 
gers in the last segments of the anterior part and in the 
blades of the swimming bristles whose fringes are very 
fine and difiBcult to see, and, last, the terminal, simple, 
ribbed bristles are finer. 

Length: 15—30 mm. Heteronereis stage, about 15 
TDia., male with two regions. 

Occurrence: Andaman Islands; Nicobar Islands, Nan- 

Distribution: Indo-China; Bay of Bengal, Arabian 
Sea, Persian Gulf, Red Sea.

(?) Platynereis integer, Treadwell, 1920, p. 595, fig. 4. 

Atocous condition still unknown. Heteronereis stage: 
Prostomium snout-like, protruding, broadly rounded in 
front. Tentacles small, ventral, pointing backwards; the 
palps have a similar disposition, but concealed under the 
head and lowered over the mouth. Four enormous eyes 
with lenses, the anterior pair much larger than the pos- 
terior and nearly ventral in position. Proboscis: group 
1=0; II=chitinous areas destitute of paragraphs; 111= 
pectinate cluster; IV=crescentic clusters of small pectinate 
denticles; V=0 (or 1?) ; VI=on each side a round or oval 
cluster of pectinate paragnaths; VII— VIII a row of seve- 
ral oval clusters. Tentacular cirri reaching backwards to 
the 6th— 9th segment. Anterior dorsal cirri of the male 
swollen, the succeeding ones crenulated. Two laige 
anal cirri with a filiform tip and a rosette of papillae. 
Swimming bristles compound, with long oval blades, 
bearing, on one side, below the apex, very long and spine- 
like delicate marginal teeth projecting at an angle. In 
the last segments simple setae with a ribbed blade. 

In the male specimens, the epitocous transformations 
commence on the 15th setigerous segment. The inferior 


ventral ligule has three processes and the dorsal lamella 
of the ventral cirrus is bifurcated. The last 15—16 seg- 
ments resemble a kind of narrow, slender, tail but the 
appearance is rather delusive as all these segments are 
provided v^^ith epitocous bristles and lamellae, only the 
ventral division is much smaller. The anus is surround- 
ed by a rosette of minute hollow papillae and the pygid- 
ium bears two anal filiform cirri. 

As already stated, it might be, perhaps, the epitocous 
condition of PI. fusco^ubida. 

Length: 10—20 mm. 

Occurrence: Nicobar Islands, Nankauri Harbour; 
Andaman Islands, in plankton. 

Distribution: Funafuti, Gilbert Islands (Philippine 
Islands?) , Java, Weiu Island, Indo-China, Gulf of Siam; 
Nicobar Islands, Andaman Islands.

Platynereis abnormis, Fauvel, 1932, p. 113. 

Proboscis: Group 1=0; II=a small concave row of 
paragnaths; 111=0; IV=a crescentic row of paragnaths; 
V=0; VI=a triangular row of paragnaths; VII— VIII=five 
small, transverse groups of paragnaths, three of them in 
the median part and one on each side. Tentacular cirri 
long. A very long dorsal cirrus on the 1th setigerous seg- 
ment. Falcigerous setae with sickle-shaped terminal 
pieces bent in the form of a hook with a dorsal promi- 
nence. Posterior dorsal homogomph falcigerous bristles. 

The atocous specimens resemble PI. dumerilii except 
in the characteristic, very long, dorsal cirrus of the 7th 
setigerous segment. The falcigers are also alike. The 
mutation of the feet occurs about the 14th to 15th feet 
in the male and 16th in the female, according to Augener. 
In Heteronereis stages from Trincomali he noticed three 
regions; an anterior of 14 segments, with a long cirrus on 
the seventh, a middle one of 43, and a posterior, atocous, of 
11 segments. Moreover, he mentions two other long fili- 
form cirri on the eighth segment of the posterior region. 

Length: male Heteronereis, 10 mm. 

Occurrence: Trincomali; Krusadai; Pamban; from

Nephthys oUgobranchia, Southern, 1921, p- 610, pi. XXIV, fig. 
12: Fauvel, 1932, p. 119. 

" Differs from N. polybranchia in the distribution of 
the branchiae which occur fully developed on the sixth 
foot, and disappear on the 20th to the 23rd foot, whereas 
in N. polybranchia the branchiae are larger on the fifth 
foot and persist almost to the end of the body; in that the 
branchiae contain a double vascular loop whereas there 
is only a single loop in N. polybranchia; in that the pos- 
terior lamellae of the feet are considerably surpassed by 
the spiral lobe." (Southern) . 

Remarks: As there are also several vascular loops in, 
at least, the anterior branchiae of N. polybranchia, differ- 
ences on tliat account are not of much value. Both may 
be only varieties of one species. Both live in water of 
variable salinity. The number and disposition of 
the papillae of the proboscis have not the value gene- 
rally set on them for the identification of Nephthys for 
there is often a wide range of variation.

Occurrence: Calcutta Water Works (Pulta) and Salt 
Lakes; Chilka Lake; Vizagapatam; Cochin backwater.

226. Ecoice investigatofis Fauvel. (Fig. 120, a-f). 
Eunice investigatoris, Fauvel, 1932, p 137, fig 19. 

Body cylindrical anteriorly, semi-cylindrical in the 
middle and flattened in the hind part. Palps bilobed. 
The three median tentacles are subequal and reach back- 
wards to the 6th— 7th setigerous segment; the two outer 
tentacles are hardly as long. The tentacles are all subu- 
late, slender and smooth. The buccal segment (peristo- 
mium) is thrice as long as the succeeding one. Two ten- 
tacular cirri set on a short achaetous segment. Gills from 
the 6th setigerous segment, the first one small, but already 
compound; they are very large about the 7th— 8th, with 
18—20 filaments about the 14th setiger. Well developed

on about forty segments, they decrease in size in the mid- 
body and increase again very much in the posterior 
region, where they continue to the 6th— 7th small seg- 
ments preceding the pygidium. The posterior gills are 
dichotomously branched. In the mid-body there are al- 
ready a few bifid or trifid filaments. Dorsal cirri long and 
smooth in the first segments, then shorter than the gills: 
they are not knife-like, and, except the first ones, hardly 
thicker than the branchial filaments. Ventral cirri finger- 
like in the first 5—6 feet, in the succeeding ones short and 
moniliform; they again become digitiform in the posterior 


half of the body, becoming longer and longer toward the 
Iiind part, where they are twice as long as the feet. Pygi- 
dium with two long, smooth, ventral cirri. Acicula black. 
Acicular setae black, bidentate, hooded, beginning about 
the 44th— 45th foot. Comb-setae long, narrow, with 8— 
10 teeth and equal sides, or, sometimes, one longer. 
Capillary setae long, slender, faintly winged. Terminal 
pieces of the compound setae strongly bidentate, with a 
hood not protruding above the tip, the shaft is slighdy 
enlarged. Labrum dark, with anterior edge toothed. A 
single specimen, 110 mm. long and 7 mm. broad, colour- 
less or light yellowish-grey in spirit.

figs. 10, 11: Augener, 1913, p. 284. 

Body small, filiform, rounded. Tentacles short, 
smooth or very faintly annulate. Gills beginning very far 
from the head, about 80th— 100th foot or even farther 
back. They are simple, or consist of two fiaments. Comb- 
setae and acicular setae present. Prostomium broad, 
slightly notched in front. Eyes large, reniform.

chiate foot X45; 6, foot, with simple gill X45; c, foot with bihd 
gill X45; d, posterior falciger X380; e, acicular bristle X380; 
/, comb-seta X380. 

Length: 20—60 mm. 

Remarks: The gills coimnence very far back from the 
head, at first small and simple, occurring very irregularly, 
except in the posterior region, where they consist of two 
filaments, and are longer than the dorsal cinrus; they are 
missing on incomplete specimens and on the young. Such 
was the case in Crossland's and Augener's specimens. 
The genus Nicidion differs only from Eunice in wanting 
gills: but already in several so-called Nicidion, which 


proved to be only varieties or anomalies o£ Eunice species, 
gills were found in adult specimens, very far from the 
head. Thus Nicidion gracilis is, perhaps, a young speci- 
men, or a variety, of E. marenzellen Grube, as AT. edentulum 
is a variety of E. siciliensis Grube. 

Occurrence: Mergui; Gulf of Mannar. 
Distribution: Australia, Indo-China; Indian Ocean, 
Mergui, Gulf of Mannar, Zanzibar.

ous segmeMs; they are all pinnate, the third pair often 
smaller. On the anterior segments;, the dorsal lamellae 
are large, oval, or sub-triangular, the 5—6 first ones sub- 
equal, the 4th often larger. The following lamellae are 
lower, more rounded or heart-shaped, gradually decreas- 
ing in size, but still conspicuous to the end of the body. 
Ventral lamellae smaller, a* first oval, next rounded and 


then very small. No noteworthy transverse ridges. In 
the anterior region dorsal and ventral setae long and 
capillary. In 3—4 segments, from the 10th setigerous, on 
the ventral ramus a large golden seta, curved and dotted. 
From the 17th— 18th setigerous segment ventral hooks 
with 3 teeth above the main fang. Dorsal hooks froin the 
40th— 42nd setigerous segment. There are no genital 
pouches. A median anal cirrus and two very small others.

Disoma orissae, Fauvel, 1932, p. 174, fig. 29, a — m. 

Prostomium elongated, slightly notched in front, bul- 
ging in the middle and ending behind in a aest reaching 
to the 2nd setigerous segment. On the raised part, four 
very small eyes, two dorsal and two lateral, and a small 
erect, tapering, median tentacle. On each side, at the hase 
of the prostomium, a small proiecting nuchal organ. On 
the first setigerous segment a large lanceolate, sobulate, 
dorsal cirrus and a ventral one directed forwards; a small 
bundle of capillary setae in front of the dorsal cirrus, and 
a fan-shaped ventral bundle of much longer setae extend- 
ing beyond the prostomium. On the 2nd setigerous seg- 
ment dorsal and ventral cirri, triangular, mucli smaller 
than the first ones, and ventral setae of two types: (1) an 
anterior row of very fine capillary setae and (2) a poster- 
ior transverse row of stouter shorter bristles withi blunt 
curved tips. Dorsal setae absent. On the 3rd setigerous 
segment, a large lanceolate, chopper-like, dorsal cirrus, a 
crescentic tip, a triangular ventral cirrus, smaller than the 
dorsal one, a small ligule under the ventral cirrus and, in 



front of the parapodial lamella, a vertical row of 7 stout 
yellow acicular setae with blunt bent tips, an anterior row 
of slender capillary setae and, in front of the cirrus, a 
diverging fascicle of dorsal capillary setae. In short, the 
ventral setae of the second foot are shaped like those on 
the third, but the acicular bristles are smaller, paler and 
more hyaline. Between the third and fourth foot, a deep 
triangular notch on each side oi the body divides the 
anterior part from the following region in which the first 
6—7 segments are much larger than the others; as a result,

this region is enlarged and flattened. On the 4th setiger- 
ous segment, the first of the enlarged part though smaller 
than the next, the dorsal and ventral cirri are thick, 
rounded lamellae, and there is a bundle of dorsal and 
ventral setae. The condition is the same in the succeed- 
ing four segments, but the ventral bristles are large, stout, 
yellow, set brush-like, as in Aricia, and of two kinds: (1) 
stout, doubly curved, nearly sickle-shaped, with a broad 
wing showing a tendency to split into fine spines, (2) capi- 
llary, similar to the dorsal ones. The dorsal setae dis- 
appear about the 11th foot. From the 9th segment back- 
wards the dorsal cirri become filiform and the ventral 
ones are modified about the 12th-13th feet. Beyond the 


11th foot long filiform ventral papillae make their appear- 
ance, a single one at first under each foot, but increasing 
to 2, 3, or 5. From the 9th foot backwards, the ventral 
setae are of two kinds: (1) stout, straight, bodkin-shaped, 
and (2) very slender capillaries. 

Length: about 6 mm. by 1 mm. 25 segments, incom- 
plete behind.

The specific characters are mainly those oi the genus. 
It is very doubtful whether there is really more than 
one species, although many have been described, but the 
characters used to discriminate them are of very little 
value. Specimens exhibit a great deal of variation which 
is probably a result of frequent autotomy, followed by 
more or less complete regeneration; individual specimens 
also present an extensive range of variation, for instance, 
the characters given by Crossland as distinctive of Ch. 
longimanus are often met with in Ch. variopedatus from 
the Atlantic Ocean and English Channel. Ch. longipes 
is only a young form of the same. The number and size 
of the anterior segments vary to a very large extent, as 
also the length of the feet.

Two protractile cushion-shaped nuchal organs. Peristo- 
mium achaetous. Proboscis huge, campanulate. Seg- 
ments divided into four rings, nearly smooth on the ven- 
tral side, rough and corrugated on the dorsal. In the 
first four setigerous segments, the dorsal ramus carries, in 
front of a bundle of long capillary setae, large curved 
adcular setae with a hook at the tip. Of the other dorsal 
and ventral setae some are capillary, slender and smooth. 


while the others are shorter and slightly bent. In the 
succeeding segments, the dorsal and •ventral rami are simi- 
lar, and in the form of thick rounded processes, without 
cirri, and each bearing a bundle of capillary setae and 
shorter, forked, setae with limbs unequal and ciliated on 
the inner edge. From the 29th setigerous segment to the 
last one a short slender finger-like process is inserted above 
the ventral ramus. In the last segments this process reach- 
es one-fourth or one-third of the breadth of the body. 
A lateral organ lies between the two rami. There are six 
pairs of branchiae from the 2nd to the 7th setigerous 
segment, arborescent, densely ramified as in Scalibregma. 
The first pair, the smallest, has 6—7 filaments, the four last 
ones are sub-equal and much larger. They are inserted 
behind the dorsal setae. Pygidium short, with broad ter- 
minal vent and 6 anal cirri : I dorsal, I ventral and 2 
on each side. 

Length: 35 mm. by 3 mm. 

Colour: Discoloured in alcohol, with the exception 
of the reddish-carmine eye-spots. 

Occurrence: Mergui Archipelago, Paway Island; Gulf 
of Mannar, Krusadai Island.

Notomastus zeylanicus, Augener, 1926a, p. 172; 1927a, p. 218 
(non WiUey?). 

The characters of the one species are those of the 
genus. The body slender, fiHform, without any appa- 
rent difference between the thorax and the abdomen, is 
very like that of an Oligochaete. 

Length: 15 mm. by 0.8 mm. 

Occurrence: Vizagapatam. 

Remarks: Augener identifies this species with Noto- 
mastus zeylanicus Willey (1905) , but I very much doubt 
their synonymy. 


Thorax with seven setigerous segments, bearing dorsal 
and ventral capillary setae. On the 8th and 9th segments 
ventral hooks and a dorsal copulatory organ with modi- 
fied large spines. In the abdomen dorsal and ventral 
hooks and dorsal cirriform gills.

Body slender, filiform, slightly enlarged in the thorax; 
about 200 segments or more. Skin faintly tessellated in 
the anterior segments. Prostomium blunt conical, without 
eyes. Peristomium achaetous, short ventrally and over- 
hanging the prostomium on the dorsal side where it is 
twice as long. The first 8—9 segments biannulate, larger 
and more swollen than those following. Maximum 
breadth about the 6th segment. The first 7 setigerous 
segments bearing each two dorsal and two ventral bundles 
of capillary setae. On the 8th and 9th segments ventral 
hooded hooks and a dorsal copulatory apparatus armed 
with 8 large, bent, acicular spines (two in each ramus) 
converging towards the boundary of the two segments 
between which opens the male genital pore. In each dor- 
sal ramus there are two bristles, a long one and a shorter 
supplementary seta. An ovate gland lies between the 
posterior bristles. From the 10th setigerous segment 



backwards dorsal and ventral hooded hooks. In the ab- 
dominal region the body is semi-circular in section. 
Dorsal and ventral uncinigerous tori are short, little rais- 
ed, transverse pads. About the 80th setigerous segment

Genus PULLIELLA Fauvel. 

Body divided into three distinct regions: (1) thora- 
cic, the 9 segments of which bear only capillary setae in 
both rami; (2) abdominal, with hooks in both rami and 
dorsal tori well apart; (3) posterior with dorsal acicular 
setae and ventral hooks. The last segments are partly 
fused together. Pygidium with two stout, conical, ventral 
cirri. Branchiae absent.

pattern and each carrying two dorsal and two ventral 
bundles of capillary setae, inserted into hollow (retractile?) 
eminences. In the next three segments, the dorsal and 
ventral hooks are arranged in transverse rows, faintly 
raised but not forming true tori. The following abdomi- 
nal segments bear two short prominent dorsal tori well 


apart. The first ventral tori are longer than, and closer 
to, the dorsal tori; next they become nearly as short as 
the dorsal tori. The posterior region numbers 8—11 seg- 
ments, larger than the preceding ones, short, conspicuous, 
separated from each other by a nau-row and deep constric- 
tion. They carry, on the dorsal side, stout, bodkin-like 
acicular setae, arrayed in two rather wide apart rows; 
and on the ventral side hooks like those of the abdomen. 
Pygidium on the ventral edge of the last setigerous seg- 
ment, with two stout, conical, diverging cirri under the 
anus. On the 4th— 5th abdominal segments, a dorsal 
raised swelling between the tori and somewhat behind 
them. There are no branchiae. 

Length: 15—25 mm. by 2—3 mm. 

Remarks: This species is a connecting link between 
Scyphoproctus and the other Capitellids. 

Occurrence: Pulli Island, Gulf or Mannar.

Remarks: In the Maldanidae the head, anterior seg- 
ments, and the pygidium, provide the most important 
features which differentiate species and genera. Petalo- 
proctus and Nicomache differ mainly in the structure of 
their pygidium, whilst the head and anterior segments are 
almost alike. Incomplete specimens can, therefore, be 
hut exceptionally identified with certainty. Unfortunate- 
ly) Maldanidae are very brittle worms and are often in- 
complete in the collections.

straight or faintly curved. Anal plate oval, slanting, with 
the rim notched on each side, smooth or faintly crenate 
on the ventral side. Anus dorsal, puckered under the anal 
plate border. No acicular hooks on the anterior seg- 
ments. Uncini with a strong hooked end. Numerous 
denticles on the vertex, and sub-rostral filaments. A thick

Remarks: The variety tropica Monro differs only 
from the type in the absence of a glandular crescent on 
the dorsal surface of the 5th setigerous segment, but that 
is also sometimes absent in specimens of M. sarsi from 
the north seas. Maldane cristate Treadwell has a high 
keel, a deep cephalic pouch and a denticulate ventral bor- 
der of the anal plate, but these characters are also fre- 
quently met with in typical M. sarsi, the anal plate being 
very variable. Moreover, the cephalic pouch is always 
present, more or less deep but often inconspicuous, its 
anterior dorsal edge being appressed on the head, especi- 
ally on specimens dead in uieir tubes.

Body sausage-like, narrowed in the middle, expanding 
at both ends. The anterior segments often retracted into 
the following ones. Densely coated with small filiform 
papillae. Prostomium reduced to a mere small knob. 
Shield plate divided into two unequal parts by a slanting 
line and marked with ridges and striae. 

Length: 10—30 mm. by 8—10 mm. 

Colour: greyish. Shields purple, violet or red or 
dark. Gills red. 

Occmrence: Burma, Mergui; Andaman Islands; Chil- 
ka Lake, plentiful in mud ; Ganjam Coast, Madras. 

Distribution: Pacific Ocean, Japan, Petchili, New 
Zealand, Australia; Indian Ocean; Atlantic Ocean, Medi- 
terranean Sea; Arctic Seas. 

Remarks: Having had the opportunity to compare 
specimens of Stemaspis from the gulf of Petchili with 
those of India, Indo-China and Europe, I have failed to 
find any constant differences between St. costata Marenzeller 
and St. scutata Ranzani. The so-called accessory plates of 
Marenzeller are only the anterior border of the shield 
plates seen under the more or less transparent skin. 


Segments few, body short, conical, divided into three 
regions: (I) thoracic, (2) abdominal with biramous seg- 
ments, and (3) caudal (scapha) , very small and leaf-like,

Body often much swollen anteriorly, ventral side 
convex, dorsal concave; posterior region narrow, cylindri- 
cal. In the anterior region the skin is covered with small 
papillae, glandular, rounded, hemispherical or flattened 
and often little conspicuous. In the posterior region the 
superficial rings are often very distinct, even nearly moni- 
liform. There are 13—18 thoracic segments bearing dor- 
sal setae. A wide, frilled, prostomial lobe, eye-less and 
bearing numerous tentacular drri, some cylindrical slen- 
der, spirally twisted, others much stouter, strongly en- 
larged at the tip and grooved. A prominent upper lip, 
hollowed, spoon-like. A small triangular fleshy knob 
under the lower lip. First segment as a large Y-shaped pad 
with bent edges. The ventral shields are short, narrow, 
square, sunk into a ventral groove. They are not visible 
when the thoracic region is much swollen. Small pointed 
nephridial papillae on the three first setigerous segments, 
sometimes on the next seven; a swelling with a small cen- 
tral spot (nephridiopore?) is visible on the base of the 
foot. It appears to have 8—9 pairs of nephridia, the first 
4—5 pairs, often visible through the transparent teguments, 
being short and oval. The dorsal capillary setae, very 
slender and smooth, noticeably emerge from the long 
cylindrical foot which is slightly enlarged at the tip. Tori 
and uncini are utterly wanting, as well in the abdomen 
as in the thorax. Anus terminal, without papillae.
